The No-Till Growers Podcast Network

Mar 6, 2023

Hi everyone, it's Natalie. It's hard to believe this is my sixth episode for The No-Till Market Garden Podcast. It felt super intimidating to commit to finding and interviewing ten people, but it turns out to have been a lot of fun to talk with people I've admired from a distance and also some of my friends. For this episode, I talked with my friend and colleague, Sonja Birthisel. She is a weed ecologist and agroecologist by training, but her interests and expertise are wide and varied. We get into some of her research on the effects of tarping and solarizing on soil biology, important traits of weeds, seed predation, and her work in the community.
